SELF-HEATNG SOLDERlNG-ELON AND TORCH.

Application filed February 12, 1916.

To aZ 'it-,tow t may Concern.'

lie it known that i, Brin; itin E. i-iicnnn, a citizen of the Unit ot America, residing at Prairie rll. in the county of hariton and State of Missouri, have invented certain new and use't'ul improvements in Seltlieating Soldering-irons and Torches, of which the following is a speciiication, reference being had therein to the accompanying drawing.

This invention` relat solderingr iron and to 1ch and has 'for its principal object the production of a simple and efficient 'soldering iron which may loe supplied with gas and which may also take in air so that the mixture may be transmitted to the iame housing wherein it is ignited for heating the copper.

Another object of this invention is the production of a self-heating soldering iron and torch which is so constructed as to allow the flame of the lame housing to heat the copper, this copper being adapted to be detached when desired so as to allow the flame to positively constitute a torch.

Another object of this invention is the production of a self-heating soldering iron and torch wherein a coupling is employed for connecting the several elements together, this coupling being provided with a simple and eiiicient means for supplying air to the interior ot the device in desired quantities so that the gas oe mixed t ierewith for providing a mixture tor burning in the flame housing.

With these and other objects in view this invention consists oi certain novel combinations, constructions, and arrangements oi parts as will loe hereinafter fully described and claimed.

in the accompanying drawing:

Figure 1 is a side elevation of the heating soldering iron and torch, as

to a self-heating seltconstructed in accordance with this invention.

Fig. 2 is a central longitudinal section through the self-heating soldering iron and torch.

Fig. 3 is an enlarged longitudinal section through the central portion of the device, illustrating the manner in which the various elements are connected hy means of the coupling.

of Fig. Q, looking in the direction of the arrows.

Fig. 6 is a plan View of a portion of the device, illustrating the manner in which the collar is mounted upon the coupling.

Referring to the accompanying drawing by numerals it will he seen that the seltheating soldering iron and torch comprises the main pipe 1, upon which the grip 2 is carried. This main pipe 1 carries the valve housing 3 having a valve t to which the tube e is attached, whereby gas may be supplied through the valve housing 3 to the pipe 1. rlhe coupling o is elongated and cylindrical in shape and is internally threaded at its ends so as to he connected at one end to the pipe 1 and at its opposite end to the pipe 8, as shown at 9. rlhe gas tip 10, having an opening 11 is positioned within the coupling 6 and has its externally threaded end 12 threaded int-o the pipe 1, clearly shown in 'Fig'. 3. Thus, it will oe seen that the gas which is passed into the pipe 1 by means ot the valve housing 3 will be transmitted through the tip 10 into the coupling 6. The coupling G is provided with an opening 13 communicating with the interior thereof, and this opening 13 may be partially closed or entirely opened by means oi the collar 14 which is rotatably mounted upon the coupling. rihis collar 14 is provided with a slot 21 through which the pin 22 carried by the coupling G extends for limiting the rotary movement of the collar in either direction. rllhe collar le is provided with a .iilled portion 23 upon its periphery for Jhicilitating` the rotation of the collar when desired. lt is, of course, understood that it is intended to have this collar mounted ipon the coupling snugly enough so as to trictionally engage and bind upon the coupling at all times so that when the collar is turned to a desired adjusted position it will not move accidentally. This collar is further provided with an opening 24 of substantially the same size as the opening 13 formed in the coupling 6, and, therefore,

when the collar is rotated so as to allow thesel this slot 21 is such, however, as to prevent the openings from moving entirely from registry and, therefore, a small supply of air may be passed into the interior of the coupling at all times. This is very desirable Where it is desired to heat the copper to only a minimum degree, which Will be accomplished by the reduction of the supply of air and gas, While the provision of the air Will prevent the llame Within the housing 17Y from smoking.

' rllhe pipe 8 carries the reduced tube 15 extending throughoutits entire length so that this tube 'will communicate with the interior of the coupling 6 and as the gas and air Which are mixed Within the coupling 6 pass through the tube 15 they Will become very thoroughly mixed so that when passing from the tube 15 the mixture Will be in a condition to beV readily ignited.

The copper 16 is provided with flame housing 17 having a plurality of apertures 18 and from this flame housing there extends an integral threaded neck 19 which is removably secured to the end of the pipe 8. A s the mixture of gas and air passes from the pipe 15 into the flame housing 17 it may be ignited so as to heat the copper 16. It is, of course, obvious that the burnt gas Will pass from the flame housing 17 by means of the apertures 18. lt Yis further obvious that the point 26' of the copper 16 may be of any desired shape Vwhich may he necessary for any peculiar orV particular Work.'

`When it is desired to use the device as a torch it rvill be seen that since the neck 19 is rci'novably secured to the pipe 8, the copper and flame housing may be removed so as to allow the mixture to be ignited immediately upon passing from the tube 15, thus constituting a torch. 1

When the devi e is in operation the valve 4f may be actuated 'so as to allow gas to' pass through the valve casing 3, into the pipe 1, to the tip 10. Since this tip is provided with an opening 11 the gas ivill pass into the coupling 6, at which time the collar 14e may be adjusted so as to provide the desired amount of air for the interior of theV coupling 6, thus constituting a mixing chamber. As the gas and air pass through the tube 15, they Will become more thoroughly mixed and then passing into the flame housing they will be ignited for heating the copper 16.

F rom the foregoing description it Will be seen that a very efficient self-heating soldering iron and torch has been produced, which is so constituted as to allow the copper yand flame housing t-o be detached, whereby the device may be used as a torch, While the several elements are efliciently connected together so as to prevent their accidental displacement, vvhile the coupling Will permit the desired amount of air to pass` into the interior of the device to mix with the `gas when the collar is adjusted.

What is claimed is:

In a device of the class described, the combination with a pipe, of a gas tip comprising a neck7 said neck mounted upon said pipe, said gas tip having a discharge aperture formed therein, a coupling mounted upon said pipe and surrounding the gas tip, said coupling provided With an aperture admitting air to the interior of said` coupling adjacent to the-apertured portion of the gas tip, a collar mounted upon said Y coupling, said collar. provided with an apen ture registering With the aperture of said coupling, said collar adapted to be rotated upon said coupling for limiting the amount of air passing through the aperture of said coupling, means on said coupling and en# gaging the collar for limitingthe rotary movement of the collar a second pipe at,- tached to said coupling, said last-mentioned pipe being provided With a tube therein and with copper on its outer end, said copper provided with an enlarged flame housing,

and a neck extending inwardly from the flame housing of the copper, said neck being threaded upon the last-mentioned pipe, and said flame housing of the copper provided ivitli a plurality of apertures, substantially as shown and described.

In testimony whereof hereunto aliix my signature.
